Artificial Immune System based Firefly Approach for Web Page Classification
WWW is now a famous medium by which people all around the world can spread and gather the information of all kinds. But web pages of various sites that are generated dynamically contain undesired information also. This information is called noisy or irrelevant content. Web publishing techniques create numerous information sources published as HTML pages. Navigation panels, Table of content, advertisements, copyright statements, service catalogs, privacy policies etc. on web pages are considered as relevant and irrelevant content. This paper discusses various methods for web pages classification and a new approach for content extraction based on firefly feature extraction method with danger theory for web pages classification
Self-contained Kondo effect in single molecules
Kondo coupling of f and conduction electrons is a common feature of
f-electron intermetallics. Similar effects should occur in carbon ring
systems(metallocenes). Evidence for Kondo coupling in Ce(C8H8)2 (cerocene) and
the ytterbocene Cp*2Yb(bipy) is reported from magnetic susceptibility and
L_III-edge x-ray absorption spectroscopy. These well-defined systems provide a
new way to study the Kondo effect on the nanoscale, should generate insight
into the Anderson Lattice problem, and indicate the importance of this
often-ignored contribution to bonding in organometallics.Comment: 4 pages, 5 figures (eps
A Generalized Polynomial Identity Arising from Quantum Mechanics
We establish a general identity that expresses a Pfaffian of a certain matrix as a quotient of homogeneous polynomials. This identity arises in the study of weakly interacting many-body systems and its proof provides another way of realizing the equivalence of two proposed types of trial wave functions used to describe such systems. In the proof of our identity, we make use of only elementary linear algebra and combinatorics and thereby avoid use of more advanced conformal field theory in establishing the aforementioned equivalence

Performance Analysis of Two Receiver Arrangements for Wireless Battery Charging System
Two different arrangements for Wireless Battery Charging Systems (WBCSs) with a series-parallel resonant topology have been analyzed in this paper. The first arrangement charges the battery by controlling the receiver-side rectifier current and voltage without a chopper, while the second arrangement charges it with a chopper while keeping the chopper input voltage constant. The comparison of these two arrangements is made based on their performance on various figures of merit, such as the sizing factor of both the supply voltage source and receiver coil, overall system efficiency, power-transfer ratio, receiver efficiency, and cost estimation. Later, the simulated study is verified by the experimental setup designed to charge the electric vehicle
